13, react 3h, proceed in autoclave, in 1h, be warmed up to 180 DEG C, continue reaction 6h, naturally cool to room temperature, in this process
Forming the precipitation with layer structure, precipitate and separate, deionization is washed 3 times；The solid obtaining precipitation joins concentration
In the sodium lactate solution of 4mol/L, solid-to-liquid ratio is 1:50, stir 5h, precipitate and separate, it is thus achieved that solid be washed with deionized 3
All over afterwards, calcine at a temperature of 450 DEG C, remove lactate therein, i.e. can get a kind of magnetic ferric oxide nano piece.
Take 1g ferric oxide nano piece, join in the pending methylene blue waste water of 1.0L, add 0.01 milliliter of quality
Fraction is the hydrogen peroxide of 30%, stirs 20min, and organic matter is decomposed, and magnetic field separates, and clearance 94.3%, supernatant can be arranged
Put.
Claims (1)
1. a preparation method for magnetic ferric oxide nano piece, is characterized in that in turn including the following steps:
1) by FeCl2It is dissolved in water, is configured to the solution that concentration is 2～3mol/L, take this solution of 500mL, be placed in wherein
It in 70～80 DEG C of water-baths of constant temperature, is simultaneously added dropwise 30% (mass fraction) hydrogen peroxide 2～4mL and a certain amount of NaOH weak solution, protect
Holding pH value is 12～13, reacts 2～3h, proceeds in autoclave, be warmed up to 150～180 DEG C in 1h, continues reaction 4～8h, from
So being cooled to room temperature, forming the precipitation with layer structure, precipitate and separate in this process, deionization is washed 2～3 times；
2) joining the solid that precipitation obtains in the sodium lactate solution that concentration is 2～4mol/L, solid-to-liquid ratio is 1:10～1:50,
Stirring 4～5h, precipitate and separate, it is thus achieved that solid after being washed with deionized 2～3 times, at a temperature of 400～450 DEG C
Calcining, removes lactate therein, i.e. can get a kind of magnetic ferric oxide nano piece.
